Ink SCREEN PRINTING INK
PET (MOF) INK 9000 SERIES
PET（MOF）INK 9000 SERIES is matt-finish ink designed for membrane switches with polyester film. Conventional 9000 Series contains the ingredients which are regulated by French Mineral Oil Regulations and PFAS regulations. However, PET（MOF）INK 9000 SERIES complies with such regulations.
Properties

JA-950 10%(*3) (slow reaction, no yellowing) JA-940 10%(*4) (slow reaction, no yellowing) |
| De-foamer | JA-200 |
| Mesh | 250-300meshes/inch |
| Stencil Cleaning | Vinyl Cleaning Thinner |
| Substrates | untreated PET film, treated PET film |
| Tack-free time | 50℃hot air drying – approx.80 sec.
80℃hot air drying – approx.40 sec. 80℃box dryer(hot air circulation) – 5 min. |
| Complete drying | 80℃box dryer(hot air circulation) – 30 min |
*1 As PET (MOF) dries by evaporation of thinner, ink can be used as it is. Add Hardener to improve adhesion and properties of ink film. The mixture has pot life.
*2 JA-970 is recommended for ordinary purposes. Adhesion and chemical resistance are improved.
*3 JA-950 is recommended when weathering resistance, lightfastness or post-processability are required.
*4 JA-940 is recommended when hard ink film makes post-processing difficult. JA-940 helps ink film to be flexible.

* The weathering resistance varies depending on the color. The weathering resistance of matched colors, especially smoke colors, are much inferior to that of primary colors.
Precautions
- Be sure to dry by heat as this ink dries slowly to prevent clogging.
- When multi-layer printing is required, standard drying conditions may cause insufficient drying. In that case, please take longer drying time.
- PET (MOF) INK has semi-gloss type, which is 9100PL SERIES PET (MOF) INK.
- PET (MOF) INK 9000 SERIES has partly different thinner ingredients from that of PET INK 9000 SERIES. Its thinner ingredients comply with French Mineral Oil Regulations as well as PFAS regulation. As other ingredients (resin, additives, pigments) are the same as PET INK 9000 SERIES, there are not much differences in the performances of these two inks .Be sure to do trial print with the actual conditions before changing from conventional type to MOF type.
- Please refer to MSDS before use.
- The information herein may change or revised without prior notice.
- The data herein are based on the evaluation of our lab and do not mean any warranty of the properties when in use by the customers.
- Please be sure to use after confirming that the product fits the purposes.
